    Michelmores 5K 2026

    Earlier this month, Team Ruddlesden had another fun evening with at the Michelmores 5k, which is a great event that raises valuable money and awareness for charity, which was Hospiscare this year. Aftwerwards, in what is becoming a bit of a tradition, it was nice to catch up with our friends at AWP, over a few drinks at the Topsham Brewery.And a special congrats to Ian Curnow from Groundsure, but running for Team Ruddlesden, who won a prize for first veteran!

    Radon Protection General Requirements

    Although outside the scope of services usually provided, Ruddlesden geotechnical were able to help with a recent enquiry from a private individual. Whilst the details would need to be designed by a suitably qualified engineer, Ruddlesden were able to confirm the general principles of radon protection in ground floor slab construction, with reference to BRE Report BR211 (2023 edition): Radon: Guidance on Protective Measures for New Buildings (including supplementary advice for extensions, conversions and refurbishment projects). All staff are very familiar with this document as, given the company’s location in southwest England, where elevated levels of naturally occurring radon are commonly present, due the underlying geology, almost all geotechnical and contamination reports include a radon assessment.

    Cable Percussive Boreholes for Piled Foundation Design and Settlement Analysis

    Cable percussive boring was undertaken as part of a geotechnical investigation to determine the ground profile for piled foundation design and assess the settlement of soft and compressible ground beneath a proposed embankment at the site of a proposed residential development in Shropshire. Cable percussive boring was considered the most suitable method for this project as they facilitated the recovery of relatively soft soils to depths of up to 20m, which could not have been achieved using dynamic sampling/ windowless sample boreholes, trial pits or conventional rotary boreholes. In addition to facilitating in-situ standard penetration tests (SPTs), the cable percussive boreholes allowed undisturbed samples to be taken for undrained triaxial and oedometer consolidation laboratory testing to be carried out, for foundation design and settlement analysis.
